HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 778,874, dated January3, 1905.

Application filed January 5,1904:- Serial No. 187,820-

lu (LY/Z 1077,0117, it may concern.-

Diego, in the county of San Diego and State of California, have inventedanew and useful Hydrocarbon-Burner, of which the following is aspecification.

This invention relates to hydrocarbon-burners, and has for its object toproduce adevice of this character simple in construction, easilyinstalled and operated, noiseless in action, and in which the heaviergrades of hydrocarbon fuels may be employed.

Another object of the invention is to produce a burner capable ofinstallation without change of structure in an ordinary cook stove orrange.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter shown and described, andspecified in the claims. 7

In the accompanying drawings, forming a part of this specification, andin which like reference characters are employed to denote correspondingparts, there is illustrated one form of the embodiment of the inventioncapable of carrying the same into practical operation,

it being understood that the elements therein exhibited may be varied orchanged as to shape, proportions, and exact manner of assemblage withoutdeparting from the principle thereof.

In the drawings, Figure 1 is a plan view. Fig. 2 is a transverse sectionof the improved device applied. Fig. 3isa plan view with thespreader-plate removed.

The improved device consists of a relatively shallow priming-tray 10,having its rear side 11 extended above its front side 11 and curvedtoward the latter side to present a flame-defiector, as shown in Fig. 1,the tray being supported in any suitable manner within the firechamberof a cook-stove, aportion of which is Supported within the tray 10, asby lugs 13, is a relatively large tubular retort, which will preferablybe formed of a section of pipe 14:, such as gas or steam piping, andprovided with caps 15 16, forming closures for its ends. The retort ispositioned above the bottom of the tray 10 and likewise a short distancefrom its rear side 11, as shown, leaving a relatively larger area of thetray uncovered at the opposite side. Extending upwardly from the retortare burner-nipples 17, the nipples, it will be observed, thus comingabove the upper line of the tray '10 and'of its rear side 11, so thatfree access of air to the nipples is assured. Leading into one of thecaps 15 16for instance, the cap l5 is a feed-pipe 18 of relatively smalldiameter and provided with acontrolling-valve 19, and leading from thepipe 18 is a priming-pipe 20, the latter terminating above the trayadjacent to the side 11* and being provided with a controlling-valve 21.

Extending from the ends of the tray 10 are standards 22 23 forsupporting a deflectorplate 2 1, the latter being rendered adjustableupon the standards, as by clamp-bolts 25 and spaced apertures 26. 7

When installed within the fire-chamber of a cook-stove, with the pipes18 20 extending through apertures in the wall of the stove at one end ofthe fire-chamber, to start the fire the valve 21 is opened long enoughto permit only asmall quantity of the fuel to flow into the tray, whichupon ignition heats the retort to a sufficient degree to cause the fuelwhen admitted through the valve 19 to be vaporized and escape in theform of gas through the nipples 17. As the flame increases in extent andintensity it is deflected by the plate 24: and is caused to play overand above the upper portion of the retort and maintain the latter at asufficiently high temperature to insure a continuous. and uniformvaporization of the fuel and a correspondingly steady radiation of heattherefrom, so that the con sumption of the fuel is regular and withoutwaste, thus insuring an economical as well as a constant action.

By locating the nipples 17 above the upper .line of the tray 10 theaccess of air thereto is not obstructed. Hence the gas burns freely andwithout noise.

By elevating the side 11 of the tray the flame when the kindling-supplyflowing from the branch 20 is ignited is thereby deflected andcorrespondingly increases the rapidityand thoroughness of thevaporization and lessens the tendency to form soot and other sediment.This is due to the fact that the curved side 11 operates positively toprevent the escape of the flame in the priming-pan to the chimney, as itis well known that in all stoves vthe draft is from the front to therear, and

without the provision of the curved side the flame would have a tendencyto pass up the chimney without directly impinging the retort; but by theemployment of this curved side the flame is directed against the retortand effects its proper heating before it escapes, the result being thatthe even and proper heating of the retort is secured and conservation offuel is effected.

The retort, it will be noted, is relatively large and the feed-pipe l8relatively small. Hence a correspondingly large vaporizationchamber isprovided in which a large supply of the gas is being continuouslyformed, so that no necessity exists for gas chambers or reservoirs inconnection with the device. The vaporization being direct, the fuel isnot retarded or caused to pass through circuitous channels, and thisrenders the burner peculiarly adapted for burning the heavier grades ofhydrocarbon or liquid fuel, which require a free and direct flow to theretort and which cannot be burned in devices wherein the fuel isrequired to flow through intricate or circuitous passages or channels.

The parts may be of any suitable size and of any suitable material andmay be modified .in minor particulars, as heretofore noted,

without departing from the principle of the invention or sacrificing anyof its advantages.

Having thus described the invention, what is claimed is 1. A hydrocarbonburner comprising a priming tray having a relatively highinwardly-curved rear side, a retort disposed adjacent to the side, and aflame-deflector disposed above the retort. i

2. A hydrocarbon burner comprising a priming tray having a relativelyhigh inwardly-curved rear side, a retort disposed adjac'ent to the side,and a'vertically-adjustable flame-deflector disposed above the retort.

3. A hydrocarbon burner comprising a priming-tray having its rear sideextending above its front side and curved inward, a retort supported bythe tray adjacent to the rear side, nipples carried by the retort andextending above the sides of the tray, a primingpipe, a feed-pipe, andcontrolling-valves carried by the said pipes.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
